I am trying to upgrade a 6.2.8 to 7.3.2.
Originally, the installation was on an old Windows Server 2003, and the 6.2.8 was running fine.
We have moved to a new Windows Server 2012 to support ASP.NET 4.
After migrating, the 6.2.8 runs just fine.
I installed the 7.3.2 upgrade. I fill in the host name and password. Clicking the "Upgrade Now" link produces 2 javascript errors:
